As of pending version 4.223 of c9, a significant change will be made to c9. An existing feature (deferred payments) will be completely removed and instead be replaced with an alternative and improved mechanism that achieves the same aim.
The primary purpose of this post is to alert dealers that use the deferred payments facility so that you are aware of the change before you upgrade. Also this post will highlight how to solve an occasional spare parts selling arrangement: the ability to reserve stock for a cash customer, but not actually raise an invoice for the stock until they come in to receive the parts.
We try to avoid making significant changes to the software that modify the way the software is used for daily operation. In this circumstance, we are of the view that the existing deferred payment system is broken and it weakens the c9 product so we taken the decision to remove it entirely from c9. The primary reason why is that the solution is confusing and error prone and difficult to properly manage. We instead went with a solution that merges behaviour of customer order processing so that the same process you use to process customer orders that have been received is the same process you use to process items placed on reserve. This approach has numerous advantages which we hope will come clear to you as you use the new capability in c9.
